Frequent and unpredictable changes in COVID-19 policies and restrictions reduce the accuracy of model forecasts

open access: yesScientific Reports, 2023
Between June and August 2020, an agent-based model was used to project rates of COVID-19 infection incidence and cases diagnosed as positive from 15 September to 31 October 2020 for 72 geographic settings.

Modeling needs user modeling

open access: yesFrontiers in Artificial Intelligence, 2023
Modeling has actively tried to take the human out of the loop, originally for objectivity and recently also for automation. We argue that an unnecessary side effect has been that modeling workflows and machine learning pipelines have become restricted to only well-specified problems.

Protocol for the production of micro- and nanoplastic test materials

open access: yesMicroplastics and Nanoplastics, 2023
Micro- and nanoplastics (MNP) are ubiquitous, but little is known about the risks they pose to human health. Currently available data are of limited use for developing relevant risk assessments due to poor quality control, the lack of a standardised ...

Ontology-based modelling of architectural styles [PDF]

open access: yes, 2009
The conceptual modelling of software architectures is of central importance for the quality of a software system. A rich modelling language is required to integrate the different aspects of architecture modelling, such as architectural styles, structural

A Comparison of State-Based Modelling Tools for Model Validation [PDF]

open access: yes, 2008
In model-based testing, one of the biggest decisions taken before modelling is the modelling language and the model analysis tool to be used to model the system under investigation. UML, Alloy and Z are examples of popular state-based modelling languages.

Business Models as Models [PDF]

open access: yesLong Range Planning, 2010
Drawing on research undertaken in the history and philosophy of science, with particular reference to the extensive literature which discusses the use of models in biology and economics, we explore the question ‘Are Business Models useful?’ We point out that they act as various forms of model: to provide means to describe and classify businesses; to ...

Model fusion using fuzzy aggregation: Special applications to metal properties [PDF]

open access: yes, 2012
To improve the modelling performance, one should either propose a new modelling methodology or make the best of existing models. In this paper, the study is concentrated on the latter solution, where a structure-free modelling paradigm is proposed.

Insights from quantitative analysis and mathematical modelling on the proposed WHO 2030 goals for soil-transmitted helminths [version 2; peer review: 2 approved]

open access: yesGates Open Research, 2019
Soil-transmitted helminths (STHs) are a group of parasitic worms that infect humans, causing a wide spectrum of disease, notably anaemia, growth retardation, and delayed cognitive development.

The influence of Holmium substitution on the magnetic and mechanical properties of Nd2Fe14B: a first principle study [PDF]

open access: yesMATEC Web of Conferences, 2023
In this study, the ab initio density functional theory (DFT) approach is used to investigate the effect of Holmium (Ho) on the magnetic and mechanical properties of Nd2Fe14B magnets.
